Detailed Description for TS3312AQPR
Product Overview
The STMicroelectronics TS3312AQPR is a fixed-output series voltage reference for power-management circuits that require a 1.25V reference. It operates from an input range of 1.8V to 5.5V and has a 5 mA output current specification, with a specified output tolerance of ±0.15% and a temperature coefficient of 30ppm/°C. The device is supplied in an 8-QFN (1.5x1.5) surface-mount package and is specified for an ambient operating temperature range of -40°C to 125°C. Its 10µA supply current and 27µVp-p noise over 0.1Hz to 10Hz support use in reference, measurement, and control circuits where a compact fixed reference is needed.
Key Features
- Fixed 1.25V series voltage reference output
- 5 mA output current
- Output tolerance: ±0.15%
- Temperature coefficient: 30ppm/°C
- Noise: 27µVp-p over 0.1Hz to 10Hz
- Input voltage range: 1.8V to 5.5V
- Supply current: 10µA
- Operating temperature: -40°C to 125°C (TA)
- Surface-mount 8-QFN (1.5x1.5) package
Applications
- Fixed reference node for analog signal conditioning and measurement front-end circuits
- Set-point or threshold reference in power-management control circuits
- Voltage reference for sensor signal chains requiring a 1.25V reference
- Compact reference circuit in surface-mounted instrumentation and control boards
Design & Procurement Notes
When using the TS3312AQPR, confirm that the input supply voltage remains within 1.8V to 5.5V under all load and transient conditions, and that the reference load does not exceed 5 mA. The ±0.15% tolerance and 30ppm/°C temperature coefficient should be included in the error budget for precision analog, sensor, or power-management reference paths, while the 27µVp-p noise specification over 0.1Hz to 10Hz may be relevant for low-frequency measurement accuracy. The 10µA supply current is useful for power-conscious designs, but the 8-QFN (1.5x1.5) surface-mount package requires an appropriate PCB land pattern. The specified -40°C to 125°C ambient range should be checked against the final assembly environment.
